Spectral evolution of two-photon emission in microresonators
Francesca Famà, Stefano Dello Russo, Stefano Giaccari +14
High-Q silicon nitride microresonators are versatile sources for generating photon pairs via four-wave mixing. We investigate the spectral coherence of this process, tracking the t…
Sub-shot-noise emission statistics of a CW-excited single photon source
G. Gavello, G. Petrini, I. Ruo Berchera +8
Shot noise sets a fundamental limit on the sensitivity of classical optical measurements, with coherent emitters achieving the lowest possible shot-noise level. Emission from sub-P…
Table-top nanodiamond interferometer enabling quantum gravity tests
Marta Vicentini, Ettore Bernardi, Matteo Bordin +6
Unifying quantum theory and general relativity is the holy grail of contemporary physics. Nonetheless, the lack of experimental evidence driving this process led to a plethora of m…
Universal Protection of Quantum States from Decoherence
Francesco Atzori, Salvatore Virzì, Francesco Devecchi +6
The fragility of quantum coherence fundamentally limits the scalability of quantum technologies, as unavoidable environmental interactions induce decoherence and rapidly degrade qu…
Interplay between dressed and strong-axial-field states in Nitrogen-Vacancy centers for quantum sensing and computation
G. Zanelli, E. Moreva, E. Bernardi +7
The Nitrogen-Vacancy (NV) center in diamond is an intriguing electronic spin system with applications in quantum radiometry, sensing and computation. In those experiments, a bias m…
Experimental Test of Nonlocality Limits from Relativistic Independence
Francesco Atzori, Salvatore Virzì, Enrico Rebufello +9
Quantum correlations, like entanglement, represent the characteristic trait of quantum mechanics, and pose essential issues and challenges to the interpretation of this pillar of m…
